2. Ukutyeba kunye nolawulo lwe-rheology:
Umsebenzi: I-HPMC isebenza njenge-thickener kwaye inceda kulawulo lwe-rheology.
Ukubaluleka: Ngokulawula i-viscosity yomxube we-samente, i-HPMC inceda ukuthintela ukuhlukana kunye nokuhlalisa amaqhekeza aqinileyo.Ukwandisa ukusebenza kunye neempawu zesicelo sezinto ezisekelwe kwi-samente, okwenza kube lula ukuphatha.
3. Phucula ukuncamathelisa:
Umsebenzi: I-HPMC yongeza ukunamathela.
Ukubaluleka: Ukongezwa kwe-HPMC kuphucula ukunamathela phakathi kwemathiriyeli yesamente kunye nee substrates ezahlukeneyo.Oku kubaluleke kakhulu kwizicelo ezifana ne-adhesives tile, apho ukubambelela okuqinileyo kubaluleke kakhulu kwixesha elide kunye nokusebenza kwendawo ye-tile.
4. Seta ulawulo lwexesha:
Umsebenzi: I-HPMC inceda ukulawula ixesha lokujika.
Ukubaluleka: Kubalulekile kwiiprojekthi zokwakha ukulungelelanisa ixesha lokumisela ukuhlangabezana neemfuno ezithile.I-HPMC inokulungelelanisa ixesha lokumisela izinto ezisekelwe kwi-samente, inikezela ukuguquguquka kwezicelo ezahlukeneyo.
5. Yandisa iiyure zokuvula:
Umsebenzi: I-HPMC yandisa iiyure zokuvula.
Ukubaluleka: Ixesha elivuliweyo lixesha apho imathiriyeli esekwe kwisamente ihlala isebenza emva kokwakhiwa.I-HPMC iye yandisa eli xesha ukwenza isicelo kunye nohlengahlengiso lwezinto eziluncedo ngakumbi.
6. Ukumelana neentanda:
Umsebenzi: I-HPMC yongeza ukuxhathisa kokuqhekeka.
Ukubaluleka: Ngokwandisa ukuguquguquka kunye nokubambelela kwi-matrix ye-cementitious, i-HPMC inceda ukunciphisa amathuba okuqhekeka kwizinto eziphilisiweyo.Oku kunenzuzo ngakumbi kwiindawo apho utshintsho lweqondo lokushisa okanye ukunyakaza kwesakhiwo kunokwenzeka.
7. Nciphisa ukushwabana:
Yintoni eyenzayo: I-HPMC inceda ukunciphisa ukushwabana.
Ukubaluleka: Ukucutheka kunokubangela ukuqhekeka kwezinto ezisekwe kwisamente.I-HPMC inceda ukufezekisa umthamo ozinzile ngakumbi ngexesha lokunyanga, ukunciphisa umngcipheko wemiba enxulumene nokuncipha.
8. Isincamathelisi sethayile esekwe kwisamente:
Umsebenzi: I-HPMC isetyenziswa ngokubanzi kwi-adhesive tile ze-ceramic.
Kutheni kubalulekile: Kwimiqulu ye-adhesive tile, i-HPMC ibonelela ngokubambelela okufunekayo, ukusebenza kunye nexesha elivulekileyo elifunekayo ukufakela ngokufanelekileyo.Iqinisekisa ukudibanisa okuqinileyo phakathi kwe-tile kunye ne-substrate.
9. Ukuziphakamisa kwangaphantsi:
Umsebenzi: I-HPMC isetyenziselwa ukuzibeka phantsi komgangatho.
Kutheni kubalulekile: Kuqulunqo lokuzilinganisa, i-HPMC inceda ukufezekisa iimpawu zokuqukuqela ezinqwenelekayo kwaye inqanda ukwahlukana kunye nokuzinzisa.Inceda ukuvelisa indawo egudileyo kwaye elinganayo.
10. Udaka kunye nePlaster:
Injongo: I-HPMC ihlala yongezwa kwiidaka kunye ne-plasters.
Ukubaluleka: I-HPMC iphucula ukusebenza, ukuncamathela kunye nokusebenza ngokubanzi kodaka kunye ne-plastered ekutyatyekeni nasekugqibezeleni izicelo.
Ukusetyenziswa kwe-hydroxypropyl methylcellulose kwizinto ezisekwe kwisamente zininzi.Ijongana nemingeni eyahlukahlukeneyo ehambelana nokuqulunqwa, ukusetyenziswa kunye nokusebenza kwezi zinto, okwenza ukuba zilungele kwaye zithembeke kuluhlu olubanzi lwezicelo zokwakha.
